To whom may, concern Be it known that we, Josnrrr MALLIGAN l CHARLES ldl. liv'rns, citizens of the Un ed States, and residents of Point Marion, in the county at Fayette and State of Penn's l to an improved and more particularly to bands i connection With automobiles for ng the driving action or for check- 5 o the car.

'Iention resides more particularly in 1h Ford cars to control the reverse slow speed drives anc the brake, and on, comprehends an improved th e r objects of the invention v apparent to persons in a consideration of ation when. taken in con- -mpanying drawings,

'. s a diagrammatic sectional view .d accordance with the 1n- I I de elevation,

is an enlarged perspective view of the band in closed position and showing adjustable in operative and inoptive positions,rand 5 is a view oi? the band in an open pc tion,

nereriing to drawings in detail, 1n l1 s reference characters designate Lelllg' parts throughoutothe several -e irn'prov hand is shown as emhodying a pair of semi-circular hinged secto oi pr ier malleable or spring steel i lat; stool: and proper width and tions are disposed with rent to each other and coni toward and away from nected for 1 pecially adapted for use in connecconstruction of hand designed to facilitate,

each other by a pivot or hinge 12, the hinge plates or leaves of which are preferably riveted or otherwise secured to the outer faces of the sections adjacent to said extremities in order that the sections may swing into positions in alinement when open, or in arcs of 20 from their normal closed positions when 1n use. The sections are provided with the usual linings 13 of raybestos or other similar friction material in the form of composite interwoven fabric and asbestos or the like, and these linings may be made in one or more sections riveted to the semi-circular sections of the band, as indicated at 14.

At the free extremities of the band sections, there are disposed lugs'15 which are formed integral therewith, riveted thereto or otherwise secured in position. These blocks are arranged to extend lengthwise of the sections and they have their outer ends bifurcated to form apertured cars 16 between which the lugs 17 are pivoted transversely as shown at 18' in order to allow the In s to move to positions in alinement with the outer ends of the blocks or parallel to each other and at right angles to the blocks, as clearly shown in the drawings. The pivots 18 are preferably in the. form of rivets extended transversely through the bifurcated ends of the blocks and the adjacent ends of the lugs 17 are reduced in thickness for engagement between the serrations of the block and apertured to receive the pivots 18 as indicated at 19, while the free ends of the lugs are preferably bifurcated as indicated at 20 and the corner portions 21 rounded in order to be properly accommodated within the clutch housing or easing, especially when employed in connection with the Ford transmission assembly! 7 By way of illustration, there is shown a transmission housing or casing 22 having the the springs and the gripping action of the,

bands on the peripheries of the drums. The housing or casing 22 is preferably livith and at right angles to the made in two sections boited together as shown art :28; and in additiom is provided with on opening in the top portion closed by cover or door 29 rendering accessible the springs and adjusting nuts heretofore d: "ribcd.

i suailyfthe lugs of the friction bands are rigidly secured to the extremity of the one-piece resilient split rings forming the hands, the lugs being ape'rtured at one side and slotted at the other. it is necessary to remove the top of the transmission hous- 1115;; or casing in order" to make replacement of new linings, and necessitating detachment of numerous parts and disassemblage of the 'ing' mechanism generally, with much ex pense and with much trouble and consuma- {ion of considerable time. In the present unstaine by h-inging; the sections of the bands in the center of the band which is disposed at the bottom, and having; the lugs adjustable to suit conditions in alinement band ends or blocks disposed thereat, the re-iining and iissembling of the hands is facilitated without the removal of the top of the transmission casing or housing, but simply by removing the cover or door 29. Furthermore, it is unnecessary to disturb other mechanical parts of the transmission as is ordinarily necessary, thus making the replacement of new linings less expensive and ermltting a band to be rehned much quicker. In

practice, the nuts 27 are loosened or slackencd up from the bands, the springs 26 acting: to expand the band on the drums. The screws of the cover 29 are removed in order to permit displacement of said cover or door from the sloping top portion of the transmission housing or casing. The nuts are then loosened as specified but not entirely unscrewed or taken off. A cord is then passed around. the drum and the corre sponding band opened and the lugs folded down. The cord is then attached to the end of the bands which may he drawn out through the opening in the top of the housingbetwwnthe outside of tln transmission drums and the inside of the transmission casing. iihen the bands an applied, the hinged connection will allow for the necessary relative movements of the sections with respect to each other in order that they may sccommodsted between the drums and i messes the housing, at which the lugs are missed into position, one lug being first raised to engage its shaft, thespring compressed, rind then the other lug; raised in position. The tension of the spring may then he adjusted through the medium of the nut in order that the frictional engagement between the iin inc and the periphery of the drum. may be properly regulated.

In view of the foregoing it is thought that the operation of the device will be readily understood and in view of the simplicity and practical value that it will commend itself to those skilled in the art.

Having thus described our invention, what we claim is:

i. A friction or clutch hand comprising hinged sections having a lining, and lugs pivoted to the ends of the sectio. s diametrically opposite to said hinged connection.

2. A band of the class described comprising resilient semi-circular sections pivoted for movement in a common plane toward and away from each other, and bifurcated lugs pivoted to the free extremities of said sections opposite to thepivotal connection. and adapted for movement resrwardiyrin contact with and forwardly to project ontwardly from said extremities.

3. A. band of the class described comprising a pair of semi-circular band sections disposed when arranged with their ends in abutting relation to form a circuiar hand, a hinge connection between two abutting ends of said sections, lining sections for the band sections, blocks at the outer faces of the extremities of said band sections, and. bifurcated lugs pivoted to said blocks for movement in alinement with the hloclrs against the band sections at their peripheral faces and at right angles to ssidhlocks for engagement with an actuating shaft.

'4 The combination with a transmission housing and a drum therein; of an actuating shaft, a band comprising hinged sections engag'ed on the drum, a lining for said sections, hinged lugs at the' free extremities of saidsections and detachably engaged by said shaft, tensioning means between said lugs and mounted on the shaft, and means "for adjusting said tensioning means.
